You can forget Israel if you wish. The problem with that is to get Israel to forget Israel. Not going to happen.
I believe Iran's president is deadly serious when he calls for the destruction of Israel. I don't think he's talking simply for the edification of the Iranian masses.
I doubt that Israel's military analysts do either. If Israel is faced with the choice of pursuing the strategy of Mutual Assured Destruction with irrational jingoists and going for a first strike when no nuclear retaliation is possible-what do you think will be the choice made?
Either the Iranian leaders are covering up their peaceful intentions with genocidal threats or they are completely and earnestly serious. I believe them. I think the Israelis do also. Upon receiving reliable intelligence of an Iranian nuclear weapons program nearing completion, that leaves only one choice for Israel: remove the threat.
That doesn't necessarily mean that removing the threat will entail the use of nuclear weapons by Israel. Israel attacked Iraq's nuclear program in 1986 by conventional means. I am confident they will destroy Iran's nuclear program by conventional means if at all possible. To avoid the geopolitical consequences if for no other reason. However, if the convention effort fails, Israel will attack an Iranian nuclear weapons program with nuclear weapons if the choice is either doing that or depending upon the rationality and benevolence of the Iranian government.
Any overt nuclear "bunker buster" will a) probably hit the wrong target and b) just invite Iran and others to return the favor
.
You're making an unwarranted assumption here, i.e, the assumption that any nuclear attack would be tactical in nature or use 'a' nuclear bunker buster. If some nation decides to hit Iran with nuclear weapons over this issue, I doubt it will be 'limited' or 'tactical' in nature. If all possible targets are hit, the probability of not hitting the right targets decreases dramatically. Alternatively, if the workers in the nuclear program are all dead from blast and radiation then it is moot whether the facilities are intact or destroyed.
All Iran's hardening of its nuclear facilities does is to encourage any enemy that employs a nuclear preemptive strike to make it big enough to do a harder job.
I've seen no evidence of any great improvement in the capabilities of Iran's military since the war with Iraq. Unless the Iranian military has improved dramatically over the past twenty years, I doubt that Israel would go to a nuclear strike unless conventional military efforts failed.
It's relevant because, as I wrote in my original post, if the bungling in Iraq was comparable to Hitler's bungling in the Mediterranean, then Iran will be his Barbarossa. See the pattern?
Lobotomy Boy,
Germany getting itself into war with the three greatest polities on earth-each of which had a much greater population, more industry, more resources, and more people than Germany-is somehow equivalent to the US taking on Iran?
That's a laughable comparison. Gemans, shortly after their invasion of Russia, were facing divisions which their intelligence services had no clue existed. The Soviets could have retreated for hundreds if not thousands of miles and still possessed ports, railroads, and industrial centers sufficient to fight. Comparing Soviet Russia to Islamic Iran in military terms is laughable. Iran, faced with any formidable invasion, has none of the options the Soviets had. Some pattern.
